【摘要】 回顾了主设备在事故工况下动态响应分析的重要意义以及国内外研究的现状。对堆本体和蒸汽发生器在失水事故和地震载荷下的动态响应作了详细的分析。着重考虑载荷的确定、简化数学模型的建立、解法、有效质量、有效刚度、时间步长、持续时间,阻尼值和线性化,并对下一步工作作了安排。更多还原

【Abstract】 The important significance of dynamic response analysis for primary components under accident conditions and the research status at home and abroad were reviewed. The details of dynamic response analysis for reactor and steam generator under LOCA and seismic loading were performed. The considerations are concentrated on the determination of loading,the establishment of simplified mathematical model, the method of solution, effective mass and effective stiffness, time step, duration, damping value and linearization. The future work was also arranged.更多还原
